Yeah sharpening is fine. What I would say is to avoid IR when seeing is great. It inherently has lower resolving power (like you're using a smaller aperture scope).
i see
No
These aren't absorption bands. Only CH4 727nm, 889nm, and UV are interesting.
A touch of UV yeah, but it's mainly deep blue. You need an IR cut with this as #47's have considerable IR leak

as it still allows the UV to pass, whereas your normal UV/IR cut blocks the UV
